Last Known ActivityLTjg Richard Christian Sather was flying the first airstrike on Hanoi when he and LTjg Everett Alvarez were both shot down. Alvarez survived and held a dubious distinction as the first naval aviator POW and longest held (8.5 years) of the war. Dick Sather did not survive, and his remains were not returned to U.S. control until 1985, when he was identified at the Central Identification Lab Hawaii (CILHI).
